No anti-siphon and CO2 is affected by temperature.
This was the tank that I bought with my marker and I got to use it once before the regulator started leaking. The day that I used it was great in perspective that I got about 500 shots as advertised and it was nice and light. The on and off valve was cool since I could turn it off, degas and take my time after that.
The folks at PMI were fast and easy to deal with for the RMA so they get a plus on customer service and the product was nice to use when it was working. I'm hoping to see other people's experiences with product to see if it is a design flaw or I was just unlucky.
If it malfunctions again over the next year I'll update my review.
A regular tank with a degas on the ASA or a screw type on / off would be better based on the feedback I have received from some guys that run my local field. PMI stands behind their product without question and it did what I expected when it worked.
